PVC SG-8
ʻO ka polymer kiʻekiʻe-molecular thermoplastic i hana ʻia e ka polymerization suspension o ka monomer vinyl chloride.ʻO ke ʻano molekole:- (CH2 – CHCl) n – (N: degere o ka polymerization, N= 590 ~ 1500).ʻO ia ka mea i hoʻohana nui ʻia i ka hana plastic.Loaʻa iā ia ke kūpaʻa kemika maikaʻi, ka pale ʻana i ka corrosion a me ka pale wai.
